New Guinea Impatiens Plant Named &#39;SAKIMP043&#39;

ABSTRACT

An  Impatiens  plant particularly distinguished by having blush-pink flowers with darker splotches at the base of the petal, and green leaves, is disclosed.

Genus and species: Impatiens hybrida hort.

Variety denomination: ‘SAKIMP043’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of New Guineaimpatiens plant, botanically known as Impatiens hybrida hort, andreferred to by the variety name ‘SAKIMP043’. ‘SAKIMP043’ originated inMisato, Japan from an interspecific hybridization between theproprietary female Impatiens variety ‘NC-1H1’ (unpatented) havinglight-orange flowers and the proprietary male Impatiens variety‘NJ-1174A’ (unpatented) having lavender-colored flowers.

In January 2010, ‘NC-1H1’ and ‘NJ-1174A’ were crossed and a populationof F1 plants was created. The F1 plants were evaluated in Misato, Japanin an open-field trial. The criteria for plant selection included lightflower color, canopy-shaped plant habit, and a strong root system. Atthe completion of the trial, a single plant selection was made and giventhe experimental name ‘M2013-444’ based on the criteria above andvegetatively propagated. From June to August 2013, ‘M2013-444’ wasevaluated in an open-field in Misato, Japan. Shoot-tip cuttings of thevariety were then shipped to Salinas, Calif. where the plants werepropagated and re-evaluated for stability of traits. ‘M2013-444’ wassubsequently named ‘SAKIMP043’. ‘SAKIMP043’ was found to reproduce trueto type in successive generations of asexual propagation via vegetativecuttings in Salinas, Calif.

SUMMARY

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Salinas, Calif.

1. Blush-pink flowers with darker splotches at the base of the petal;and

2. Green leaves.

-   Classification:    -   -   Family.—Balsaminaceae.        -   Botanical.—Impatiens hybrida hort.        -   Common.—Impatiens.        -   Designation.—‘SAKIMP043’.-   Growth:    -   -   Environmental conditions for plant growth.—The terminal 1.0            to 1.5 inches of an actively growing stem was excised. The            vegetative cuttings were propagated for five to six weeks.            The base of the cuttings were dipped for 1 to 2 seconds in a            1:9 solution of DIP 'N GROW (1 solution:9 water) root            inducing solution immediately prior to sticking into the            cell trays. Cuttings were stuck into plastic cell trays            having 98 cells, and containing a moistened peat moss-based            growing medium. The cuttings were misted with water from            overhead for 10 seconds every 30 minutes until sufficient            roots were formed. Rooted cuttings were transplanted and            grown in 20 cm diameter plastic pots in a glass greenhouse            located in Salinas, Calif. Pots contained a peat moss-based            growing medium. Soluble fertilizer containing 20% nitrogen,            10% phosphorus and 20% potassium was applied once a day or            every other day by overhead irrigation. Plants were            fertilized every 2 to 3 days, 2 times in consecutive            applications and then given one clear water application.            Pots were top-dressed with a dry, slow release fertilizer            containing 20% nitrogen, 10% phosphorus and 18% potassium.
